Over the past decade, the X-ray binary research community has dedicated significant research to addressing: How do X-ray binaries form and evolve in different galaxy host environments?
As the predecessors of gravitational wave sources and millisecond pulsars and as sources which are potentially relevant in the early universe for heating the intergalactic medium preceding the epoch of reionization, understanding how X-ray binaries form and evolve has become more relevant also to the broader scientific community. The emission from X-ray binary (XRB) populations within nearby and distant galaxies, based on stacking analyses to study the average emission, has seen marked refinement over these years by adding additional parameters and more nuanced studies of the relationships between XRBs and their host galaxy properties (e.g., star formation rates, stellar masses, metallicities, and stellar ages). Additionally, studies of the XRB luminosity functions in spatially resolved galaxies have probed the XRB populations deeper by investigating different types of galaxies (i.e., early-types, spirals, irregular) and galaxy environments, such as interacting galaxies. By comparing observations with XRB population synthesis models, we have gained deeper insight into the drivers of these correlations. Additionally, both theoretical and observational studies of detailed physics, including accretion mechanisms, within XRB systems have offered important constraints for these models. Therefore, the growth of our collective understanding and access to better data has opened up new vistas and the exploration of new questions.
Here, we are soliciting papers from the science community related to XRB populations, their formation, and evolution. Particularly, we would like this Special Issue to cover topics that span XRBs within nearby galaxies (including population studies within the Milky Way, LMC, SMC, and local group) to scaling relations in distant galaxies. We welcome papers that cover both theoretical work and observational studies on this general topic and outline specific areas that we hope this Special Issue can address:
- XRBs populations in nearby galaxies—the Milky Way, LMC, SMC;
- XRBs in interacting galaxies;
- Scaling relations of XRB emission with host galaxy properties (including evolution of these relations with redshift);
- XRB luminosity functions in nearby and spatially resolved galaxies;
- Comparison of observations with theoretical models of XRB formation and evolution, including via dynamical channels (e.g., within globular clusters);
- Impact of XRBs on high-z IGM studies;
- Accretion physics models and observations using galactic or nearby XRBs;
- Ultraluminous X-ray sources and unique classes of XRBs (e.g., Wolf–Rayet XRBs, supergiant fast X-ray transients) and their relationship to other XRBs and/or their host galaxies.
